Replay got its start way back in 2003 when Jesheckah came to Sheva with a new TCG idea. Many of the TCGs that were around at that point were based around themes dealing with Japan: anime, video games, and seiyuu.

Jesheckah's idea was to create a TCG dedicated to the American music scene. So the very first music TCG, Pop Star Cards was born, with a focus on American Pop music.
Sheva quickly ended up taking over creating cards and running the website. The website grew quickly and wanted to expand to include other genres of music. The website was renamed La Musica by Danika. La Musica featured only artist decks and had a very short run for only a few months before closing down.

The TCG was finally brought back October 2005 with a brand new template and started fresh. It was also La Musica's first venture into music outside of the US. In 2006, the website went on hiatus and was given another new template that would accommodate music videos, which were a major addition to the TCG.
After some time the TCG expanded to include all forms of media relating to music: commercials, photobooks and live performances. These decks were labeled "rare decks" and were worth 2. Special decks, which included website themed decks, were bumped up to being worth 3.

In 2010, the website was revamped so that there would only be one template that matched. The overall image quality was raised so that decks would look better.
During Summer 2011, the website was closed down temporarily and given a full restart. La Musica had way too many deck types with different card values that made it far too complicated. By this time, La Musica had well over 10,000 cards. All rare and special cards were eliminated leaving the TCG with just artist and music video decks.

The website ran a contest for members to suggest and vote for a new name for the website. La Musica was renamed Replay for its 10 year anniversary.

All decks on Replay are worth 1. There are two types of decks: artist and music video. Artist decks feature soloists, bands, and band members. All musical genres are covered, the three most popular being American Pop, Korean Pop, and Japanese Pop.

La Musica started to really feel the hurt in 2010 with low quality gif formatted cards, it just wasn't the prettiest TCG out there anymore. So there was a massive overhaul of all decks to convert them to png and make all cards the same size. All artist, photobook and special decks were expanded to fit the same template used for music video and live performance decks. This was the final revamp for old La Musica before being completely rebooted as Replay.

This mini mastery will earn them one card from the member cards deck. When a player has mastered the member cards mini deck (which in essence means that they have collected 100+ member cards) they will gain the meta mastery. Attaining the meta mastery will make all member cards value change from 0 to 1, giving these players a significant boost to their card value.

With Replay's renaming and re-work the currency was also simplified. All rare deck types and the music store collectibles were trashed. Also traded music dollars in for much simpler coupons for members to get choice cards. The game pass has only really been given out once, but it allows members to email the owner to skip playing a game round and get the prize.
